This super abrasion-resistant high-pressure washing hose features a specialized water-resistant and scour-resistant synthetic rubber inner tube. Its smooth inner wall provides low flow resistance and prevents the accumulation of scale. The multi-layer high-strength steel wire winding reinforcement structure offers strong pressure resistance, effectively withstanding the continuous pulse impact of high-pressure water flow without bulging or delaminating. The thickened outer layer is made of a highly abrasion-resistant polyurethane/rubber composite material that resists sand friction, dragging, and abrasion. It is highly resistant to oil contamination and UV aging, and remains highly flexible and resistant to cracking when bent in low-temperature environments.
